Tiffani Thiessen has a sh*t ton of stuff to do and can't go on Late Night

Just the other day I was wondering what was up with Tiffani (no Amber) Thiessen. And now we know. She's so busy she can't do that damn Saved By The Bell reunion on Late Night with Jimmy Fallon, so don't ask her anymore, OK? She has a live-action cat comedy to direct!
